Mixer Config Resolution Errors
warningMixer adapter configuration errors prevent telemetry and policy enforcement from working correctly. This causes metrics gaps and policy violations to go undetected.
Monitor istio_mixer_config_adapter_info_config_errors for adapter configuration problems. Track istio_mixer_handler_handler_build_failures for handler initialization failures. Check istio_mixer_config_resolve for config resolution issues and istio_mixer_config_rule_configs to verify rules are being applied.
Review Mixer adapter configurations for syntax errors. Verify that adapter handlers reference valid adapter types. Check that all required adapter parameters are provided. Monitor istio_mixer_adapter_old_dispatch_time_datadog for performance issues in adapter dispatch. Consider migrating to Telemetry API if using Istio 1.7+ as Mixer is deprecated.
